Today we see the accuracy potential of the Hy Score 816/Diana model 6 target air pistol I recently acquired. We had a good indication from the first group it shot.

target
This group of 5 Sig Match Ballistic Alloy pellets measured 0.338-inches. Shot at 10 meters.

The test

I shot off a sandbag rest from 10 meters. The Giss counter-recoil system allows for resting the pistol directly on the bag. Despite all my complaining, I shot with the pointed sight insert I showed you in Part 1. I did have a problem with it, but it wasn’t the sight’s fault and I will explain when I get to it. read more

Today is accuracy day for the Diana Chaser air pistol. I threw in some extra tests just for fun. This should be interesting, so let’s go!

The test

I shot off a sandbag rest at 10 meters. I used the single shot tray for the first 4 groups, then switched to the magazine for the final group. There were some interesting results that I couldn’t have predicted.

Qiang Yuan Match pellets

I shot the first group with Qiang Yuan Match pellets. No particular reason for that, other than I had them ready. They hit the target low and to the left, but I left the sights where they were and shot all 10 pellets. They landed in a group that measures 1.052-inches between centers. This was larger than I had hoped for the Chaser. read more

Today is a mistake. Reader RidgeRunner asked me if I intended to finish this report from 2008. I looked at his link to Part 5 and, sure enough, it looked like I had intended to. I even promised a reader back then that I would. Well, WordPress software is at fault this time, because I did not find a later report when I entered it in the search box at the top of this page, but when I went to publish this report number 6 I found that one had already been published — on July 22, 2008. But that was after I did the complete test plus some extra things, so I’m going to finish it again. It’s actually a good report. And by the way, I just entered the title in the search box again and this time it came up. Of course it did! read more

  • Summary

Today I conduct the 25-yard accuracy test of the Chinese B3 underlever air rifle. Before shooting this particular B3 I had never shot any Chinese sporting spring rifle at this distance and I didn’t think there were any that could manage it.

The test

I read Part 6 to learn which pellets did best in the rifle. All shooting was off a rest, using the artillery hold. And I have to use the open sights on the rifle, as there is no easy way to mount a scope. Later B3s do have dovetails for scopes but this early one does not. read more

Today was day of learning, or perhaps I should say remembering, because today’s test of the Chinese B3 underlever took me back to my early days with spring-piston air rifles. I will explain as the report unfolds.

Refresher

I found this tired old air rifle in a pawn shop many months ago. In this series I have replaced the breech seal with a faucet washer, opened up the powerplant, lubricated the moving parts with Tune in a Tube and shot the rifle for accuracy. That was when I discovered how accurate this old Chinese underlever is. So I vowed to shoot it for accuracy once more, now that the powerplant has been tamed. read more

  • RWS Superdome
  • Air Arms Falcons
  • RWS HyperMax
  • Crosman Premier light
  • RWS Hobby
  • Evaluation

Today we test the accuracy of the new Umarex Strike Point multi-pump pistol. This test is the one we have all been waiting to see. The Strike Point is firmly in competition with the  Crosman 1377, and we want to know how it stacks up downrange.

The test

I shot from 10 meters off a sandbag rest. I shot 5 shots per target because this is a multi-pump. If any pellet grouped well, I would shoot another 10 shots with that pellet. I pumped the gun 4 times per shot, because the velocity test indicated that would be okay.

Sig Match Ballistic Alloy

The first pellet I tested was the Sig Match Ballistic Alloy pellet. It wasn’t tested in the velocity test, but this pellet has proved remarkably accurate in many airguns and I thought it deserved a test. Five pellets went into a 2.922-inch group. I’m not showing the dime in this photo because it makes no sense. This is a huge group for 10 meters! Also I noticed that 4 of the five pellet holes showed some tipping of the pellet as it passed through the target. read more

Things are back on track today and we will look at the accuracy of the Umarex Legends Ace in the Hole revolver. I hope it’s good!

The test

I shot from a sandbag rest at 10 meters. Ten meters is far for an action pistol, but I am trying to establish where the Ace is, in terms of hitting the target.

I wore my reading glasses so the sights would appear sharp. Single action sights work a little differently than any other revolver sights, because the rear sight is a notch in the back of the frame. The sides of this notch slope up toward the notch on both sides and I find myself holding the front sight blade a little higher than I am used to. Once I get the sight picture, though, I can do good work with an SAA. read more
